TomTom Fourth-Quarter Profit Jumps

Dutch navigation system maker TomTom has seen its fourth-quarter profits rise by 25%, beating expectations on stronger unit sales due to falling prices. Harold Goddijn the CEO of TomTom and CNBC's Geoff Cutmore discuss the numbers.

TomTom has grown rapidly in the past five years and estimates it has a 50% share of the European market, but trails behind larger rival Garmin in the United States with just a 20% share.

Last week the Cayman Islands-based Garmin said its earnings more than doubled to $180.3 million (137 million euros).

TomTom's shares fell 0.9% to 32.99 euros ($43.39) in Amsterdam trading. The stock more than doubled after its May 2005 listing at 17.50 euros, but has been held down since then by worries margins will fall as competitors such as Sony enter the market.
